🔡 Unicode Character Inspector
See the exact Unicode details of every character in your text — code point, decimal value, UTF-8 byte encoding, HTML entity and category.
| Char | Code point | Decimal | UTF-8 bytes | HTML | Category |
|---|---|---|---|---|---|
| A | U+0041 | 65 | 41 | A | Letter |
| é | U+00E9 | 233 | C3 A9 | é | Letter |
| — | U+2014 | 8212 | E2 80 94 | — | Punctuation |
| 🎉 | U+1F389 | 127881 | F0 9F 8E 89 | 🎉 | Symbol |
Every character’s exact Unicode code point, decimal value, UTF-8 byte encoding, HTML entity and category — the details a chatbot can’t reliably give. 🔒 Computed in your browser.
How the unicode character inspector works
For each character the inspector shows its Unicode code point (U+XXXX), decimal value, the exact bytes it becomes in UTF-8, its HTML numeric entity, and its Unicode general category (letter, number, punctuation, symbol, mark, space or control). It handles the full range including emoji and astral-plane characters.
A precise reference tool that a chatbot approximates and often gets wrong — LLMs routinely misreport code points and byte encodings. Useful for developers, encoding debugging, and understanding exactly what a piece of text contains.
Frequently asked questions
What is a Unicode code point?
The unique number assigned to a character, written U+ followed by hexadecimal — for example “A” is U+0041 and “🎉” is U+1F389. It identifies the character independent of how it is stored.
What are UTF-8 bytes?
UTF-8 is how the character is stored as bytes: ASCII characters take one byte, accented Latin two, most other scripts three, and emoji four. The inspector shows the exact byte sequence.
What is the HTML entity?
A way to write the character in HTML by its number, like é for “é”. Useful when a character can’t be typed directly or must be escaped.
Does it handle emoji and rare characters?
Yes — it iterates by code point, so multi-byte emoji and astral-plane characters are inspected correctly rather than split into surrogate halves.
Is my text uploaded?
No — the inspection is done entirely in your browser.
